How important is the tie-in between LVS and extraction?
A. There will always be multiple tools for simulation and analysis of the design, but there are tremendous benefits in using closely-tied verification and extraction tools. Both must use and operate on process model information from manufacturing, and both perform an extraction process on the design. LVS extracts the intended devices and parasitic extraction extracts the unintended resistances and capacitances that occur. Using a single-tool flow for verification and extraction provides results that are consistent across this flow. Calibre LVS and Calibre xRC use the same data and rule files and Calibre xRC reads Calibre LVS structures directly.
